建立了反相高效液相色谱法定量分析混配除草剂制剂中苄嘧磺隆和精噁唑禾草灵的方法。采用Kromasil C18柱(25cm×4.6mm×5μm),流动相为乙腈-水梯度洗脱,检测波长为254nm,线性相关系数为0.9992与0.9996。苄嘧磺隆和精噁唑禾草灵的加标回收率分别为95.8%和95.4%;变异系数分别为0.015和0.016。
A method was established for the quantitative analysis of bensulfuron and fenoxaprop in mixed herbicide formulations by reversed-phase high performance liquid chromatography. A Kromasil C18 column (25 cm × 4.6 mm × 5 μm) was used with a mobile phase of acetonitrile-water gradient. The detection wavelength was 254 nm and the linear correlation coefficients were 0.9992 and 0.9996. The recoveries of bensulfuron-methyl and fenoxaprop-p-ethyl were 95.8% and 95.4%, respectively. The coefficients of variation were 0.015 and 0.016, respectively.
